Answer:
Methods of obtaining a sample of 600 employees from the 4,700 workforce:
Part A: The type of sampling method proposed by the CEO is Convenience Sampling.
Part B: When there are equal number of participants in both campuses, stratification by campus would give a more precise approximation of the proportion of employees who are satisfied with the cleanliness of the breakrooms than stratification by gender. Another method to ensure that stratification by campus gives a more precise approximation of the proportion of employees who are satisfied with the cleanliness of the breakrooms than stratification by gender is to ensure that the sample is proportional to the proportion of each campus to the whole population or workforce.
Step-by-step explanation:
A Convenience Sampling technique is a non-probability (non-random) sampling method and the participants are selected based on availability (early attendees). The early attendees might be different from the late attendees in characteristics such as age, sex, etc. Therefore, sampling biases are present. All non-probability sampling methods are prone to volunteer bias.
Stratified sampling is more accurate and representative of the population. It reduces sampling bias. The difficulty arises in choosing the characteristic to stratify by.
Answer:
Total seashells = (6g + 10) seashells.
Step-by-step explanation:
Given that Mario collected 3g seashells.
Given that Jasmine collected 10 more seashells that mario. It means she collected (3g+10) seashells.
It says to write the number of seashells they collected together in terms of g.
Total seashells = Mario's seashells + Jasmine's seashells.
Total seashells = 3g + (3g+10).
Total seashells = 6g + 10.
Hence, Total seashells = (6g + 10) seashells.
Answer:
putting value of m and n in the equation we get
10x5+ 4x2
= 50+8=58
hi
here is the method :
you take Value 1 and Value 2
And you do : ( Value 2 - Value 1) / (Value 1 ) * 100
Here we have : Value 1 = 352 000
Value 2 = 337 920
So now we apply :
( 337 920 - 352 000 ) / ( 352 000) * 100 = -4
Population decreased by by 4 %
You can also make :
352 000 * X = 337 920
X = 337 920 / 352 000
X = 0.96
if the multiplier is 0.96 , it's mean that we lost 1 -0.96 = 0.04
which mean - 4%
X = number of weeks
1 week =
3x = $90
Divide by 3
3x/3 = x
$90/3 = $30
1 person = $30 per week
x 5
5 people = $150 per week
x6
6 people = $180 per week
